ProQuad (Measles, Mumps, Rubella and Varicella Virus Vaccine Live) is a combined, attenuated, live virus vaccine containing measles, mumps, rubella, and varicella viruses.
ProQuad is a vaccine indicated for active immunization for the prevention of measles, mumps, rubella, and varicella in children 12 months through 12 years of age.
ProQuad is administered subcutaneously.
The first dose is usually administered at 12 to 15 months of age but may be given anytime through 12 years of age.
If a second dose of measles, mumps, rubella, and varicella vaccine is needed, ProQuad may be used.
This dose is usually administered at 4 to 6 years of age. At least 1 month should elapse between a dose of a measles-containing vaccine, such as M-M-R II.
At least 3 months should elapse between a dose of varicella-containing vaccine and ProQuad.
A third dose of MMR might be recommended in certain mumps outbreak situations.
